Nonsteroidal Anti-Inflammatory Drugs (NSAIDs)
If you have kidney disease or kidney failure, taking both
NSAIDs and
quinapril may add to the damage that your kidneys are already experiencing. Also, NSAIDs may decrease the
blood pressure-lowering effects of quinapril. Talk with your healthcare provider about using NSAIDs and quinapril together.
Potassium Supplements
If you are taking a potassium supplement and quinapril, the levels of potassium in your blood may become too high. This can cause serious problems. Talk with your healthcare provider about using potassium and quinapril together.
Potassium-Sparing Diuretics
If you are taking both quinapril and a potassium-sparing diuretic, your body may metabolize them differently than intended and/or increase the levels of potassium in your blood. Your healthcare provider may choose to monitor your progress closely.
Lithium (Eskalith, Lithane, Lithonate, Lithotabs)
If you are taking both quinapril and
lithium, your body may metabolize the drugs differently than intended and increase the lithium levels in the blood. Your healthcare provider may choose to monitor your serum lithium levels more frequently.
Tetracycline (Sumycin, Achromycin, Wesmycin)
Taking both
tetracycline and quinapril together may decrease the amount of tetracycline in the body. If you are taking quinapril and are prescribed tetracycline, let your healthcare provider know. He or she may choose to monitor your situation more closely, consider another antibiotic, and/or adjust your dose of quinapril.
